IMPROVEMENT 1N DEVICES For REMOVING L'|ME,.DIRT. AND SEDl-MENT FROM someuoums.

Specification forming part of Letters Patent No. 115,367, dated May 30,1871.

I, ALoNzo J: SIMMoNs,of Indianapolis, in the county of Marionand Stateof Indiana, have invented certain Improvements in Extracting Lime, Dirt,and Sediment from Boiling Fluids, of which the following is aspecification, reference being had to the accompanying drawing and tothe letters and figures of reference marked thereon making a part of thesame. The nature of my said 1n vention consists in the construction ofsuch a vessel as will, when it is placed in another vessel containingany impure boiling fluid, by means of its peculiar construction andarrangement, cause that portion of the fluid which itcontains to remainso nearly at rest thatthe motion of the liquid while boiling willdeposit therein the precipitated lime, sediment, and dirt light enoughto becarried by the thermal currents; saiddevice .to be made of anyconvenient metal, such as iron or brass.

To enable others skilled in the art to make and use mysaid invention, Iwill proceed to spectively, by dand e. In the bottom of this box orvessel are two holes, one at each end, represented, respectively, by mand m of Figs. 3 and4, to allowa free flow of the fluid into the vesselso that it will not float. c c is an inside lid or bottom, perforatedwith slots, as

represented in FigNo. 1, and fastened alittle For the the end of thevessel, and into the forks f, h, k, and l. The position in which thislid is held is further represented in section by e, and the forks whichhold it by k and l of Fig 3. Be

. tween this lid 0 c and the edge of the vessel is left a convenientopen interval, as represented in Fig. 1. V

- The device here represented is to be used for collecting lime andsediment in horizontal cylindrical steam-boilers. It is to be placed itin the boiler at the point of greatest heat,

which is usually opposite the bridge-wall of the furnace, where aconcentrated flame impinges upon the boiler. The thermal currents metalof the boiler, naturally flow from the bottom to the surface of .thewater. That portion of these currents generated beneath the bottom ofthe vessel 0. I) will be deflected sidewise and flow upward around thesides of the vessel. When they have passed above the edge of the vesselthe pressure of the surrounding water will again deflect them to wardthe center of the vessel, above which they will meet and form an eddy.

Now, if the lid 0 c be of the proper relative proportion to the vesselto b, the motion of the eddying thermal currents will be so obstructedas to hold the water inside of .the vessel 0. bbelow the lid 0 ccomparatively quiet and still; their the scales, lime, dirt, andsediment which the'thermal currents have carried upward and around inthe eddies above the vessel a b will, partly by their own gravity andpartly on account of the downward motion of the eddies, fall through theopen intervals in I and around the plate 0 0 into the still water in thevessel a b, where they will remain undisturbed.

As the thermal currents are always shifting around through the boilerall substances light enough for them to carry, they will gradually inthis way deposit almost all of the solid impurities of the water in thevessel a b. This vessel can, by openingthe boiler, be removed, cleaned,and replaced at pleasure. This vessel will work equally well in otherkinds of boilers by constructing it to accommodate their form.

It has been found that in all boiling fluids, such as sirups, oils,dyes, extracts, and the like, the precipitated and solid impurities arereadily deposited in a vessel constructed upon the principles hereexplained, and thereby separated from the fluids.

What I claim, and desire to secure by Letters Patent, is-- A vessel,constructed and used upon the plan and'principle herein described, forthe purpose of extracting impurities from boiling fluids. r

In testimony that I claim the foregoing as mine I have hereto set myhand this 24th day of March, 1871.
